Configuration

Swift Performance AI offers over 200 options, but it has the ability to automatically configure itself. Although you do have the option to adjust the settings, in most cases, you don't need to touch them.

In contrast, LiteSpeed Cache has 170+ options, which require manual configuration. It is highly customizable down to the smallest details, but the admin interface is not very user-friendly, making it difficult to navigate, and it requires adequate knowledge to use properly. It's easy to make mistakes and mess up the website with it.

Page Caching

LiteSpeed Cache offers a basic preload feature that has some options, however users need to manually configure the cache lifespan preload, which might requires some technical knowledge.

Swift Performance AI is using sophisticated algorithms that automatically prioritize URLs and manage cache lifespan. Furthermore, it implements multi-level optimization to expedite cache preloading.

The utilization of Swift Performance fragments permits dynamic content, such as Gutenberg blocks, Elementor widgets, and shortcodes, to be loaded on cached pages. This facilitates the use of caching for logged-in visitors while simultaneously displaying the admin bar and loading the appropriate prices for multi-currency shops. It operates similarly to LiteSpeed ESI, but with greater ease of use.

CSS Optimization

LiteSpeed offers advanced CSS optimization, with the only inconvenience being that it is limited by the Quick.cloud quota. Using LiteSpeed for CSS optimization may also cause compatibility issues or disrupt the layout of the website, requiring manual tweaking and expertise to resolve.

Swift Performance AI creates a reliable and efficient Critical CSS that's specific to each URL to ensure that all pages function smoothly without any manual tweaks required. The best part is, there's no limit to the generation of Critical CSS - it's unlimited!

What's more, Swift Performance AI can use the Critical CSS it generates to enhance page performance for logged-in users, regardless of whether logged-in caching is on or off. This makes certain that both logged-in and non-logged-in users get to enjoy the same benefits of optimized CSS.

JavaScript Optimization

Swift Performance's AI technology is capable of removing render-blocking scripts by offloading them from the main thread. Plus, Swift Performance's script optimization works great with themes, plugins, and third-party services, and it optimizes JavaScript automatically without any manual setup.

On the flip side, LiteSpeed Cache's script optimization is considered outdated and requires manual tweaking.

LiteSpeed Cache simply delays scripts until user interactions, which can lead to false positives in testing tools and frequently results in cumulative layout shift (CLS) for real users.

Image Optimization

Swift Performance AI offers a free and unlimited automated image optimizer that is capable of optimizing third-party and background images.

The image optimizer in Swift Performance uses a WebP-first approach and can resize images to fit the appropriate device size without relying on a CDN or JavaScript. It optimizes images on-the-fly, thus avoiding the need for unused image sizes to take up disk space.

LiteSpeed Cache includes an image optimizer feature, but users are required to configure and activate it manually. However, the built-in optimizer doesn't have the ability to automatically adjust the image sizes based on the device viewport, which can result in less-than-optimal images being served to users on different devices.

Video & Iframe Optimization

Video & Iframe Optimization

LiteSpeed Cache provides the option to lazyload iframes, but it may not be able to handle dynamically added iframes, and it does not utilize placeholder images for embedded content.

In contrast, Swift Performance AI offers a comprehensive set of optimization features that includes the ability to optimize dynamically added iframes, as well as embedded content from popular services like Google Maps, Youtube, and Vimeo. This allows for more efficient loading of embedded content on web pages.

I just tried the new AI version, and I must to say it is a wonder!

It configurates itself automatically, my site went from C to A after I installed it.

Absolutely recommended!

With the release of Swift Performance AI, with just a few clicks, top page speed values are achieved that were not even achieved with the older Pro version, let alone those of other competitors.

Before Swift Performance Pro, I was alternating between WP Rocket, WPTC and Cache Enabler. But after reading reviews on Swift Performance Pro, I bought a license and have been delighted every since.

10/10 – Will buy again

Brings smile on your face ivica
I was using a lot of free caching plugins for our sites and tried some of the very well known Premium ones.

However, neither of these come close to Swift’s Pro plugin’s all-in-one uniqueness, innovations and overall speeding up sites in so short period of time after you install it on the site.

I’ve tried a dozen performance plugins, many of them actually making page loads worse. This simple plugin is fantastic. Brought a C rated site to an A. Thank you!
